14 Application example
The antenna is of a quarter wave type and is dependent on the groundplane area to complete the antenna
function. The antenna performance is also dependent on the size of the groundplane.

Placement of the antenna
The antenna shall be placed on a groundplane area, preferably at the edge of the PCB oriented as
above.
Placement of 2.4 GHz module
To avoid losses in the strip line, the module shall be placed as close to the antenna as possible.
Strip line
The strip line must be dimensioned according to your specific PCB. ( see fig 1). No crossing strip lines
are allowed between the strip line and its ground plane.
Via connections
To avoid spurious effects, via connections must be made to analogue ground.
Component matching
Component values are depending on antenna placement, PCB dimensions and location of other
components.
DC Block
Might be needed depending on RF Module configuration.
Clearance
Front surface: Minimum clearance to other components, C = 2-5 mm. Back surface: Components
allowed.
Casing material
No metal casing or plastics using metal flakes shall be used, avoid also metallic based paint or laquer.
Note ! Incorrect implementation of the antenna will affect the performance.
